在 Symfony 中设置 CsvEncoder 分隔符

Question

我想解码 csv 文件，但其中一些有“;” 作为导致错误对象的分隔符。使用以下代码逗号分隔的 csv 文件正确解码：

https://symfony.com/blog/new-in-symfony-3-2-csv-and-yaml-encoders-for-serializer

// instantiation, when using it as a component
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Encoder\CsvEncoder;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;

$serializer = new Serializer([new ObjectNormalizer()], [new CsvEncoder()]);

// instantiation, when using it inside the Symfony framework
$serializer = $container->get('serializer');

// encoding contents in CSV format
$serializer->encode($data, 'csv');

// decoding CSV contents
$data = $serializer->decode(file_get_contents('data.csv'), 'csv');

我尝试在解码函数中将上下文设置为参数：

$context = array(";", '"', "\\", ",");

$data = $serializer->decode(file_get_contents($file), 'csv', $context);

并作为构造函数中的参数：

$serializer = new Serializer([new ObjectNormalizer()], [new CsvEncoder($context)]);

两者都尝试没有任何不同的结果。

我让它以这种方式工作：

$context = [
    CsvEncoder::DELIMITER_KEY => ';',
    CsvEncoder::ENCLOSURE_KEY => '"',
    CsvEncoder::ESCAPE_CHAR_KEY => '\\',
    CsvEncoder::KEY_SEPARATOR_KEY => ',',
];

$serializer = new Serializer([new ObjectNormalizer()], [new CsvEncoder()]);
$serializer = $this->get('serializer');
$data = $serializer->decode(file_get_contents($file), 'csv', $context);

Answer 1

对于 Symfony 4，好的语法是：

$serializer = new Serializer([new ObjectNormalizer()], [new CsvEncoder()]);
$datas = $serializer->decode(file_get_contents($csvPath), 'csv', [CsvEncoder::DELIMITER_KEY => ';']);

尝试这个：

$context = ['csv_delimiter' => [",", '"', "\\", "."] ];
